Another day, another consensus algorithm. Why IBFT 2.0?

PegaSys is launching its Pantheon 1.0 release in late February. This blog is part 1 of our 1.0 Release series highlighting our IBFT 2.0 feature. In part 2 we will write about our new permissioning feature. Consortium blockchains are different to the public Ethereum mainnet in that they consist of a smaller number of nodes […]

Ethereum Explained: Merkle Trees, World State, Transactions and, More

At PegaSys we understand that entering into the Ethereum world can be a daunting task. There are many new concepts and terms that one needs to learn to engage in the community. In Ethereum Explained our protocol engineer, Lucas Saldanha, provides an easy to digest summary of the Ethereum Yellow Paper for technical and non-technical […]

What We Learned from Auditing Our Ethereum Client

At PegaSys, we take security and code quality seriously. That’s why we commissioned an independent auditor to review our codebase before we published our Pantheon Core release at Devcon4. The auditor Trail of Bits completed the security review in October. First, this audit reinforced the importance of staying on top of technical debt. Several of […]

What we learned from our first Enterprise Ethereum Hackathon

A Recap from PegaSys in Prague A few weeks ago at Devcon, we released Pantheon, our new Ethereum client written in Java with an Apache 2.0 license. To celebrate the release of Pantheon Core, we ran our first hackathon, in Prague, and invited builders from the Ethereum and Java community to participate. We were joined […]

Why We Rebuilt Ethereum from Scratch

PegaSys, the protocol engineering team at ConsenSys, is excited to announce the open source release of Pantheon Core. We have been working on Pantheon Core as part of PegaSys’s mission of building enterprise-grade solutions in tandem with the Ethereum community.

Scaling Consensus for Enterprise: Explaining the IBFT Algorithm

Consensus algorithms are one of the core innovations of blockchain, and yet also one of the most confusing. Satoshi Nakamoto created a version of Proof of Work (PoW) that was implemented as a means for simultaneously securing and validating Bitcoin transactions.

Open Leadership at PegaSys

All over the news, employees at tech companies are increasingly pushing to have a say in business and strategic decisions. The Trump administration’s immigration policies, for example, have proven especially controversial, and many engineers have gone so far as to protest or issue petitions over whether to sell AI to ICE and provide cloud services to the Pentagon that could be used for drone strikes.

Signals in the Noise: Simplifying Ethereum for Enterprises

More than Just Math: Takeaways from the ZKProof Workshop

The crypto community is teaming up with academics and industry players to develop cryptographic standards for mainstream adoption. Guest post from our R&D cryptography lead, John Brainard. Zero-knowledge proofs (ZKPs) have been getting a lot of attention lately.

Blockchains and Interoperability

Richard Brown of R3 recently wrote of his admiration for the public chainvision of Ethereum, but also noted that its current scaling and privacy challenges are too great and that “[o]nly the Corda network can deliver this.”
